CENTRON® Polyphase Meter Technical Reference Guide
Physical Description
The CENTRON Polyphase meter Personality Modules snap into the meter register
mounting brackets to ease installation of the board.
The LCD module is connected to the metrology board using the board-to-board connector.
The following information is sent to the LCD module from the metrology board:
Reference voltages
Energy data
Basic status information
A connector is located at the 12 o'clock position behind the LCD for resetting the energy
register. This is done using the ZRO-C2A Resetter.

Registers
Kilowatt Hours
The modules display energy in increments of whole values of kWh. Standard operation for
all modules is to add forward and reverse energy flow. Therefore, if the meter is inverted,
the registers will accumulate in the forward direction, thus providing uni-directional
operation. At the time of order, the LCD module can be selected to have a detent register.
Programmed at the factory, this feature will cease registration while the meter is inverted, or
power flow is otherwise reversed. The module can also be selected to have a net register.
This feature is factory programmable and will subtract registration while the meter is
inverted, or power flow is otherwise reversed.
